Hard water affects many households around the UK. Left untreated, hard water causes limescale build-up on your kettle, pipes, shower and appliances. This can cause increased wear and tear – needing more maintenance and money to run efficiently.
If you’re fed up of scrubbing white residue or dealing with itchy skin and dull clothes consider investing in a water softener.
In this guide we cover the best UK water softeners, how they work and which system you should pick for your home.
What Is A Water Softener?
A water softener is a device that takes minerals out of your water. Minerals like calcium and magnesium cause water to become hard water, which can leave you with limescale.
The most common type of water softener uses ion exchange to trade hardness minerals for sodium. This leaves you with softened water all around your home.
Benefits of installing a water softener include:
- Reduced limescale buildup
- Longer lifespan for appliances
- Softer skin and hair
- Cleaner dishes and glassware
- Reduced use of cleaning products
Why Hard Water Is a Problem in the UK
Large parts of the UK, especially southern and eastern England, experience very hard water. Over time, this can cause problems such as:
- Blocked pipes and plumbing
- Reduced efficiency of boilers and heating systems
- White marks on taps, sinks, and shower screens
- Increased energy bills
A reliable water softener can help protect your home and improve water quality.
